RAILRQAD-TIE.

SPECIFICATION formingpart of Letters Patent No. 625,153, dated May 16, 1899. Application filed January 26, 1898. serial No. 668,070. No modeL) To all whom it May cancer-7t:

Be it known that I, HARRY J. DONAGHY, a citizen of the United States of America, residin g at Gallery Junction, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Rail road-Ties, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in railroad-ties, and has for its object to provide a metallic tie,together with novel and effective means for fastening the rail thereto.

The principal feature of myinvention consists of two clamps which are substantially similar in form and which are secured in position on the tie by a common bolt. One of these clamps when secured in its position is stationary, while the other is su fliiciently cut away to permit its swinging upon the securing-bolt in order to disengage it from the flange of the rail, and thereby permit the removal of the said rail.

The device is particularly adapted for bridge and overhead work, although it may be advantageously employed for usein the laying of ordinary tracks.

The clamps which hold the rail are brought to their position on the tie by passing the same over the end, and one of these clamps is movable upon its securing pin or bolt suflieiently to allow the flanges of the rails to pass between the two clamps, when the removable one is then tightened tohold-the rail in position.

WVith the above .and other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more specifically described, and particularly pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like letters of reference indicate similar parts throughout the several views, in

whichand c.

View of one of the ties, showing clamps in position and a portion of the rail in side elevation. Fig. 31s a perspective view of the removable clamp. Fig. 4: is a similar view of the stationary clamp. Fig. 5 is a side view of a portion of the tie with the clamps in position, showing rail in cross-section.

Referring to the drawings, a designates the tie, which in the illustrations herewith is shown in the form of an I-loeam, although the fastening device for the rail may be as readily applied to other shapes or forms of a metallic tie. In Fig. 1 these ties are shown resting upon the stringers b, which would be the construction employed in overhead or bridge work. The rail 0 is secured in its position upon the metallic ties by means ,ofclamps d The clamp d has arms or brackets d formed integral therewith, that are provided on their free ends with an eyelet d to receive the fastening-bolt f, passing through the said eyelets and the web a of the tie. These two arms or brackets d' converge toward each other at their free ends, so that the space between the same will be the same thickness as the web of the tie, and the clamp is placed in position by inserting the upper flanged portion of the tie between the arms or brackets d underneath the clamp portion (1 and sliding the clamp along the tie until the desired position has been reached. The clamp c has also formed integral therewith arms or brackets e, which have an inclined portion 6 that conforms to the incline on the underneath side of the upper flange of the' tie,the free ends of these arms or brackets being likewise provided with eyelets e to receive the fastening-boltf, the distance between the free ends of the two arms being equal to the width of the web and the width of the two arms (1 at their free end. When the free ends of the arms or brackets of the clamps'are mounted upon the fastening-bolt f, they are securely held in position by means of the nut f, which is mounted upon the bolt f and bears against the arms or brackets, as shown. The shape of the arms or brackets e will of course depend upon the exact form of metallic tie which is used, that shape being shown herein conforming to the shape of the ordinary I-beam.

The clamp e is placed on the tie in a like manner to that heretofore described for the clamp d, and the back of the clamp is sufliciently cut away to permit the inclining of the same, as shown in Fig. 1, and thereby allow the flanges c of the rail to pass between the two clamps. After the rail has been placed in position this clamp e is forced inwardly, so that it will firmly engage the flange c of the rail, and is there locked by means of the nut f on the securing-boltf. I preferably employ a plate g of rubber or othersuitable material between the two clamps, upon which the base of the rail rests, although this may be readily dispensed with, if desired.

Although the foregoing appears to embody the preferable form of my invention, yet I do not Wish to limit myself to this exact construction, as various changes may be made in the details of construction without departing from the general spirit of my invention.

I claim as new, and desire to secure by Letters Patent, is

In combination with a metallic tie, a fas tening means for securing the rail thereto, said means consisting of a clamp d, and a clamp e, brackets formed integral with each of said clamps, the former of said clamps being rigidly secured to said tie and the latter being adapted to swing upon a bolt passing "through the web of the tie and through the brackets of both clamps, and a nut engaging said bolt to fasten the same in position and hold both'clam ps in engagement with the railflanges, substantially as shown and described.

In testimony whereof I affix my signature in the presence of two witnesses.

HARRY J. DONAGHY.
